wonder if anyone can help...
We had some banging noises a week or so ago and suspected the pump was the problem. We have microbore pipes and the pump looked pretty old. I gave it a knock with a hammer and it worked for a few more days then gave up the ghost - so i have now replaced it - like for like.
It was a good fit with no leaks and i set the pump speed to the same as the previous one. However when i started the heating up the pipes starting clanging and whooshing and our Glow-worm fuelsaver Mk2 boiler pilot light goes out after 10 mins or so.
Have bled air from rads and pump, but to no avail.
I suspect corrosion, sludge in the pipes...(The old pump looked pretty bad). Is this the case? How do i tackle it? Is a power flush necessary?
Please help.
